Effect of nitrogen and phosphorus fertilization on yield and some growth parameters of sudangrass (Sorghum sudanese)‎ crop

الملخص EN

A field experiment was conducted to study the effect of nitrogen(0,200 and 300 kgNha-1) and phosphorus (0,60,and 180 kgPha-1) fertilization and their combination on yield and some growth parameters of sudangrass(Sorghum Sudanese).

(Number of leaves per plant, plant height, number of heads per plant, weight of 1000 seeds, ,yields of seeds , dry weight of shoots and protein content in seeds)were measure .

Results indicated that nitrogen and phosphate application and their combination had significant effects on all growth parameters and yield of Sudangrass .

The combination treatment of 300kgNha-1 plus 180 kgPha-1) gave higher yield (71.86 gm.plant-1) and protein content in seeds( 5.79 %) and other growth parameters.
